Schoolgirls' Underwears as Hidden Uniforms.

2. A Slip with Straps for Schoolgirls after Formative Years, One of Obsolete Schoolgirls' Underwears.

Before 1990s, most schoolgirls had wore Chemises as thier underwears as "hidden unifroms" until they began to wear thier brassieres.

After they began to wear their brassieres, they wore strapped slips as underwears.

a Chemise, a strapless slip is not worn together with a brassiere, so schoolgirls after formative years bought thier strapped slip together with thier brassiers when they began to wear brassieres.

• Most strapped slips for schoolgirls' underwears also made up of two parts, a higher part around the chest made of cotton and a lower part than the chest made of chemical fibers.

Today, both a Chemise, a strapless slip and a strapped slip are obsolete, and a slip is often confused with a camisole, however, a train of a slip is not so short as a camisole.
